Design of a new concentrating solar system and implementation of a stirling engine and generator units

In this thesis, a new beta type Stirling engine model has been developed by using Matlab-2012a simulation program. For the first time, this engine combined with a new permanent magnet generator with three-phase. In the model, in order to obtain electrical power from the solar energy, at a constant temperature, but at different pressures (1-5 bar), the electro-mechanical and thermo-mechanical properties of the system are improved by the engineering performance and the efficiency of use. In the study, for engine and generator; various physical experiments are done such as pressure-volume relation, rotational speed-working-gas relation of rotor, torque relation of rotor produced by engine, pressure-volume relation tests, temperature of working gases (helium and air media) and rotation speed of rotor. The results are supported by theoretical models. In the sımulation, the designed engine is able to produce 1.5 kW power at 600 K temperature under 1 bar pressure. In the experiments, the power under a certain pressure and under high temperature ıs obtained as 270 W. In experimental and simulation helium and air are used as working gas in the closed volume. As a result, it is seen that helium working gas provides at least 5 times better electrical power than that produced by air. In addition, the GPS device to absorb a large amount (DNI), a two-stepper motors, one for each coordinate, and a dual-axis solar tracking using the gear box is designed.
